Previously, the transitory state only needed and valid during generation of the LLVM IR for the function body was conflated with the general codegen metadata for the function declaration in IrFunction. There is further potential for cleanup regarding the use of gIR->func() and so on all over the code base, but this is out of scope of this commit, which is only concerned with those IrFunction members moved to FuncGenState. GitHub: Fixes #1661.
